The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. This slim 30 mm model achieves its refined proportions through OMEGA's innovative Co-Axial Master Chronometer calibre 8751, certified at the industry's highest standard by the Swiss Federal Institute of Metrology (METAS).
Crafted in 18K Sedna™ Gold, this model has a symmetrical polished case and features a screw-in caseback with wave-edged design.
The linen dial is sun-brushed, PVD colour-treated and lacquered, with a circular date window at 6 o’clock. It is highlighted by 11 boat hull-shaped indexes and redesigned faceted hands, with the minute hand tapering to a delicate point. All the applied elements and hands are in 18K Sedna™ Gold, while the indexes and hands are also filled with white Super-LumiNova which emits a blue glow.
The watch is presented on an integrated 18K Sedna™ Gold bracelet with beautifully rounded polished-brushed links, a foldover butterfly clasp, and OMEGA’s easy comfort-adjustment system.
Sedna™ Gold
OMEGA has been using the exclusive 18K SednaTM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, SednaTM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.
Sapphire Crystal
To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
The advantages of this watch
Inside this timepiece are the revolutionary components that guarantee the highest standards of performance. From the Co-Axial escapement for long-lasting precision, to the silicon balance spring for superior anti-magnetism, OMEGA has conquered every challenge that matters.
